Reversible visual field loss in glaucoma following ventriculoperitoneal shunting for normal pressure hydrocephalus.
Article in BMJ case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We report a case of visual field deterioration in previously stable open-angle glaucoma which resolved upon ventriculoperitoneal shunting (VPS) for coexisting normal pressure hydrocephalus (NPH). A woman in her 80s with bilateral open-angle glaucoma developed apparent progression of existing glaucomatous field defects, despite stable disease and consistent intraocular pressure control following bilateral trabeculectomies over a decade prior. She was concurrently diagnosed with NPH and underwent VPS. Following VPS, visual fields returned to a previously stable baseline.Visual field fluctuations may occur concurrently with NPH, a condition affecting intracranial pressure (ICP). Here, we report visual field worsening temporally associated with NPH onset and a rare association between VPS and field improvement in the context of prior trabeculectomy. VPS may improve visual fields in post-trabeculectomy eyes by reducing ICP, thereby narrowing the translaminar pressure gradient. Unexplained visual field changes in well-controlled glaucoma should prompt consideration of pathologies affecting ICP.
